FinOps for SREs: Cutting Costs Without Breaking Things Tags: aws finops sre reliability devops Most FinOps advice starts with a cost dashboard. This series starts with a different question: how do we cut costs without violating our SLOs? I'm an SRE at a subsidiary of one of Korea's largest tech comp
In Part 1, I told the story of building OpenLoop — an open-source feedback platform — by emailing an AI agent for 5 days. 160+ emails, $15 in tokens, zero lines of human-written code, and a working product at the end. Now let's talk about what I actually learned. Let's start with the positive, becau

If your database is the heart of your application, Redis is the adrenaline. When we hit 50,000 users, our PostgreSQL instance began to sweat. CPU usage was spiking, and read-heavy endpoints were dragging the whole system down. We realized that the fastest database query is the one that never happens
You accumulate knowledge constantly — notes, docs, project decisions, things you'll need to remember later. AI agents could help you work with all of this. But how do you give them access to what you know? There's a growing industry around "agent memory" — vector databases, embedding pipelines, retr

Introduction Finding the most frequent element in an array might seem simple, but doing it efficiently is the real challenge. This problem introduces a powerful technique called the Boyer-Moore Voting Algorithm, which solves it in linear time and constant space. Given an array arr, find the majority
If you've ever given an AI agent the ability to execute shell commands or run code, you've probably had that moment. You know the one — where you check the logs and realize your agent just tried to curl something it absolutely should not have, or worse, it rm -rf'd a directory you cared about. I hit
Introduction This problem is a classic example of using Binary Search to efficiently find a value within a given range. Instead of checking every number one by one, we reduce the search space by half at each step. Problem Statement We are given a number between 1 and n. We need to guess the number u
Before pilots ever sit in a real cockpit with 200 passengers depending on them, they crash — hundreds of times — in a simulator. They experience engine failures, crosswinds, bird strikes, instrument malfunctions. They fail safely until they can't fail at all. Product teams have never had that. You b
Glossary: terms used in this article 🔸 MICA (Memory Invocation & Context Archive): A governance schema for AI context management. Defines how context should be structured, trusted, scored, and handed off across sessions. 🔸 Provenance Registry: A structured, hash-anchored record of where each conte
For decades, the tech industry chased the myth of the “10x Developer.” We looked for that rare unicorn who could out-code a small team. But today, that myth has been shattered by a much more imposing reality. We aren’t looking for 10x anymore. We are witnessing the birth of the Super Software Engine

Discover critical tradeoffs for ethical, AI development and future alignment. HOW IT WORKS Understanding the emergent field of AI safety requires a cl
While building a real-time messaging system, I ran into something frustrating: The WebSocket shows “connected”… but nothing works. The Problem Network switches (WiFi → Mobile) The connection stays OPEN, but: messages don’t send From the UI → everything looks fine What “Connected” Actually Means WebS
Introduction String problems are very common in programming, and one of the most basic yet important problems is checking whether two strings are anagrams. This problem helps build a strong understanding of character frequency and hashing. Problem Statement Given two strings s and t, return true if
I spent months building a complete document scanner app in Kotlin with Jetpack Compose. 110 files. 21,000+ lines of code. Along the way I hit problems that no tutorial prepared me for. Here are the hard parts and how I solved them. The "auto-capture" feature sounds simple: detect when the document i
While testing different AI coding tools, I kept running into two recurring problems. The first one was cost. Using the same model to plan, implement, review, test, and document does not make much sense. Not every stage requires the same level of reasoning. The second problem was more important: when
Find Minimum and maximum in an array Given an array, find: min val max val Code class Solution: def getMinMax(self, arr): min_val = arr[0] max_val = arr[0] for num in arr: if num max_val: max_val = num return [min_val, max_val] Line-by-Line Explanation Initialize min and max min_val = arr[0] max_val
